Design studies of three layer HIS design for L-band frequencies

This paper presents design studies of three layer high impedance surface for three different structures (prototypes) with and without vias for L band application. High impedance surface zero reflection phase and surface wave band and current density are few important aspects taken into consideration for comparing three HIS structures for different antenna applications. Transverse electric and transverse magnetic modes are realized from dispersion diagram. Dispersion diagram of three HIS structures is realized by Eigen mode solver. Design and simulation of three layers HIS is performed using CST v.15.
